Huttlin | August 20, 1991 |
In a container (12) a treatment space (14) for substance (16) is arranged, therebelow a wind chamber (22) and between the two a sieve bottom (80). Beneath the sieve bottom (80) a rotor (40) having a circular rotor disc (42) is arranged which is rotatably drivable about an upright central axis (A). The rotor (40) comprises at least one opening (44) which is elongated in approximately radial direction and which allows a gas stream (50) from the wind chamber (22) to pass through the sieve bottom (80) upwardly into the treatment space (14). The sieve bottom (80) comprises approximately radial blades (82) which are each arranged in an at least approximately vertical plane immediately above the rotor disc (42) in such a manner that they conduct the gas stream (50) in a sharply defined sector upwardly. In each sector-shaped gas stream (50) which has passed through the sieve bottom (80) distributed over the radial length thereof and rotating therewith on rotation of the rotor (40) nozzles (76) are arranged for spraying the substance (16) in the treatment space (14).
